My last lobby tournament match. I didn't think I would lose from this position with full hp and he only had 6 cards in hand (one of which I knew was the 0pp spell). In hindsight, I should've used demonic call and kill the last fairy on the board since he needed that exact lethal. I wanted to save my own board space though because I wanted to summon the big shikigami next turn...
My topaz was showing so much this tournament. I misplayed so often. This wasn't even the only time I gave my opponent their only out to win the game...
